8.45 Ramblr: Making Reassembly Great Again

paper slides video

简介

静态二进制重写在逆向工程中有许多重要的应用，例如补丁、代码重用和插桩。Reassembly 就是静态二进制重写的一种有效方法（Reassembly is the process of assembling a set of instructions obtained through disassembly and which were certainly patched or modified）。

本文提出了一种新的 binary reassembling 的方法，并实现了工具 Ramblr。该方法首先将原始的二进制文件反汇编，正确识别符号和预期的跳转目标，插入必要的补丁，然后将程序集重新组装到修补后的二进制文件中。
